Application filed May 24, 1919. Serial No. 299,572.

To all whom it may concern Be it known that we, l/VrLLrAr-r BARTHOLQ- MEW and GEORGE Simone, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Cylinder l t ashing Machines, of which the following is a specification.

This invention relates to washing machines of the type in which a rotary cylinder is mounted to revolve within a casing. Such machines have usually been constructed with the cylindrical walls of its cylinder and casing built up of staves, and with ends or heads to which the staves are secured, the frames which support the machine and which carry the hearings in which the cylinder rotates being attached to the heads of the casing, and a pair of trunnions or stub- 20 shafts being secured to the heads of the cylinder to support it in said bearings. Warping of the wooden structure tends to disturb the relative positions of the frames and so distort the cylinder bearings as to throw them out of alinement, thereby causing the trunnions or shaft-ends to bind in their bearings, andthrowing the gearwheel, which revolves the cylinder, out of the plane of the driving pinion which intermeshes therewith. I

The present invention seeks to overcome these difficulties by providing cylinder bearings which may assume proper relationship to the trunnions or stub-shafts of the cylinder, notwithstanding distortions that may develop in the wooden parts of the structure, and to render the mounting of the driving pinion so adjustable upon the frame as to admit of the pinion being accurately related to the driven gear wheel in any position which the latter may assume.

Accordingly, one feature of the present invention consists in providing supports for the cylinder bearings which are, within suitable limits, adjustable on the frames both angularly and bodily in a plane parallel to the axis of the cylinder, thereby insuring alinement of the two spaced bear ings in one plane, and each of which sup ports receives its bearing through the medium of acylindrical saddle having its axis of generation transverse to the axis of the washing cylinder, and thereby adapted to shift t e bearing in a planefcoincident with through spherical contact faces, such contact faces on one of the members being preferably sub-divided into three reduced areas symmetrically distributed, as in the surface of a sphere, so that while giving universal adjustment to the bearing and the pinion which it is to carry, it will insure proper seating of the attaching base by the threepoint contact.

Y The invention will be fully understood upon reference to the accompanying drawings, in which- Figure 1 is a vertical axial section of a washing machine of the kind for which the present invention is particularly designed;

the intermediate portions of the cylinder and casing being omitted.

Figure 2 is an end elevation of the same, viewed from the right of Figure. 1.

1 represents the cylinder and 2 the casing.

of a cylinder washing machine; and 3 represents the frames secured to the ends of the casing as at 4 and 5. Attached to the heads of the cylinder 1 are the stub-shafts or trunnionsb, and these turn in the babbitts or bushings 7 carried by the boxes or bearings 8, which may abut against the attaching flanges 9 of the trunnions to receive end thrust of the cylinder, and which are in turn carried by the supports 10 interposed be tween the bearings or boxes and the frames 3, the parts being secured in position by clamping bolts 11. As thus far described the parts are of known construction.

In order that the bearings 8 may shift in the vertical plane of the axis of the cylinder, and so avoid binding upon the trunnion-6, said bearings are formed with saddles 8 that meet the supports 10 through the medium of will be seen more clearly upon reference to Figure 3, and as suggested by dotted lines in said figure, fit loosely in the bearings 8 and supports 9, and also in the slots 12 of the frame. This permits the bearing support 9 to shift angularly with relation to the axis of the cylinder, as well as bodily from side to side with relation thereto With the above-described method of sup porting two spaced bearings for a shaft, or for two alined shafts or trunnions on a cylinder, the coaxial relation of the two bearings may be accurately established either in original assembly of the machine, or at any time when it may be desirable to compensate for deterioration of parts of the structure upon which the bearings andshaft are mounted, as it is obviously simply a matter of loosening the clamping bolts 11, revolving the cylinder until the bearings accurately aline themselves with the axis of the cylinder and the cylinder turns freely without binding in its bearings, and then. retighten- 1 ing the clamping bolts to secure the parts in the position which the have assumed.

In order to properly relate to a shaft, such as the shaft 6, another shaft laterally offset therefrom, such, for instance, as the shaft 14, and carrying a gear wheel 15 that must intermesh with and transmit power to or from a gear wheel 16 on the first mentioned shaft 6, the present invention supports the bearing 17 of the second shaft through a mounting which comprises an attaching base 18 carrying the bearing and a seat 19 carried by the frame of the machine, or, for instance, the ofiset arms 3*, 3? of the frame the attaching base 18 and the seat 19 being made to meet in the surface of a sphere. In order to insure accurate seating of one part upon the other without the expensive process of grinding or machining the relatively large spherical surfaces 18 and 19, said surfaces are arranged to contact through three relatively small sub-divisions of contacting area, as, for instance, by forming three bosses 20 on one of the members. In this way a firm seating may be obtained through the me dium of surfaces produced by the process of casting without the expense of finishing. B y this arrangement it is obviously easy to establish parallelism between the shafts 14L and 6 by sliding the member 18 upon the member 19 in the vertical or horizontal direction, or in any direction intermediate thereto, and by rotating the member 18 upon the member '19, and about the center of the sphere of which the contacting surfaces form a part, the spacing of the shafts may be determined at will. Thus the mounting for the bearing 17, which carries the shaft 1%, has subs-tans tially universal adjustment. in order to hold the members 18 and 19 together, bolts 21 are employed which pass through said members, as shown in Figure 3; said members 18 and 19 being provided with slots 22 and 23 which receive said bolts, and the elongation of said slots being in directions at right angles to each other in order that the parts may move relatively when the belts are loosened and adjustment is required. Dowel holes 21 (Figures 3, 5, and 6) are prefer ably also provided in the members 18 and 19 for initially positioning them. I

In order to adapt the last-named feature of the present invention for use in the special form of drive desirable in cylinder washing machines. namely, to support the reverse driving gear 24, said base is provided with an arm 18 extending outwardly and upwardly in position to receive the outer bearing of said driving gear or the outer end of the shaft 14; upon which said drivinggear is mounted, and this insures the positioning of th e driving gear along with the gear wheel 15. 26 represents a locking dog of known construction adapted to cooperate with the gear wheel 16 to hold the same in fixed position when access is being bad to the washing cylinder; and 2'? represents a gear wheel shield or guard which is subdivided into two parts lying on opposite sides of the locking dog 26, being secured byv bolt 28, preferably the bolt upon which the locking dog26 is pivoted, on the bracket 29. Bracket 29 being secured by itsfiange 29 to thehead of the casing 2, which in a'washin'g machine is usua y of wood, and the gear wheel 16 being supportedupon the frame 3 which is also attached to the casing, it is difficult to keep the parts in proper relation, and it frequently occurs that the guard, applied for protection against a wheel such as the wheel 16, will be distorted in its relation to the wheel and cause chafing of the parts in use. In the present instance, the shield 27 receives bolt 28 through the slots 28 which permit adjustment of the shield in a directi'onsperpem dicular to the plane of the wheel 16, and so adapts the shield to be positioned at any time in proper relation to the wheel, notwithstanding unavoidable distortion of the caslng upon which the parts are mounted.

In a cylinder washing machine, the combination of a cylinder rotatably supported and having a gear wheel through which it is driven, a driving shaft having a gear wheel through which it transmits power to the cylinder gear wheel, two spaced bearings for the driving shaft, and a mounting arm carrying both said bearings and comprising an attaching base carried by the inner end of the arm and a seat for said attaching base carried by the machine; said attaching base carried by the inner end of the arm and seat meeting through the medium of spherical surfaces and having means for adjust ably holding them together.
